BOD Calculations.https://discussions.probrewer.com/showthread.php?80471-BOD-Calculations&goto=newpost

We have the restrooms down stream of the brew house and have sampling points where everything converges and at the point of discharge.

We have the restrooms down stream of the brew house and have sampling points where everything converges and at the point of discharge. They will be checking our BOD and comparing it to my reporting every so often.

We are considering a couple pre-treatment options, Side Streaming obviously but I have also been looking at several treatment options including Ozone, Chlorine, and Chlorine Dioxide to reduce BOD.

My questions are:

Is there a way to calculate actual BOD with a one time sample basied on DO rather than using DO with the BOD5 formula?

How would the ORP potential of an oxidizing chemical affect the calculation?
